Description	Not Available Phenology of greater yam (Dioscorea alata L.) was studied by planting two greater yam varieties viz., Sree Keerthi and Sree Karthika for three seasons ( 2013, 2014 and 2015) at ICAR-CTCRI, Thiruvananthapuram, Kerala. Sree Keerthi took 16 to 23 days for sprouting, 88 days for tuber initiation, 236 to 243 days for senescence, which lasted for 24 to 39 days. Sree Karthika took 17 to 28 days for sprouting, 83 days for tuber initiation, 236 days for senescence which lasted for 26 to 45 days. Active tuber development was noticed between 6 to 8 months of planting ( 180 to 240 days). Timely planting resulted in more tuber yield in Sree Keerthi (26.4 to 31.5 tha-1) than Sree Karthika (22.65 to 29.3 tha-1). Delayed planting although resulted in early emergence and tuber initiation, senescence was also early resulting in yield loss in both the varieties. However, Sree Keerthi resulted in less yield loss compared to Sree Karthika, indicating its suitability for delayed planting. Not Available
